I didn't order them yet. Was hoping you'd have good luck with the Reo bottle so I could order tubing and everything right from Reo mods instead of trying to piece everything together like the creator of the box didIf you modify the bottle space only. The front door and/or the back of the case need to be shaved, to get the door to fit flush. The bottle will squeeze in from side to side, but its too tight in my opinion. You might want to give you're Japanese bottles a try?
